In fact, it was line 2836.
I just commited those changes to SVN (r4894).
This bug should be considered fixed if it does not re-occur.

As of r4893, I believe changing wikipedia.py line 2810 to:
        'source':      re.compile(r'(?is)<source>.*?</source>'),
would solve the problem.
There was an unclosed '<' after 'source'.
I'm not absolutely sure about this as testing this problem doesn't seem
easy. It also occurred to me but I can't precise under which conditions.

It looks that the error only occurs when interwiki is run with -autonomous
switch. For example runnig this command in pl.wiki: 
interwiki.py -start:100BASE-FX -autonomous
casues bot to run thru multiple pages giving in the end following error:
[[100 dni Napoleona]]: [[ja:????]] gives new interwiki [[he:m'h hymym]]
[[101 (liczba)]]: [[ja:101]] gives new interwiki [[ms:101 (nombor)]]
